ASRock is readying a new high-end socket LGA1156 motherboard based on the Intel P55 chipset, the P55 Extreme4. Designed to be a notch above the P55 Deluxe3, which packs two SATA 6 Gb/s and two USB 3.0 ports, the Extreme4 uses two 2-port controllers to drive four SATA 6 Gb/s ports, and two USB 3.0 controllers to drive two USB 3.0 ports on the rear panel, and two ports by internal headers (for the latest cases that come with USB 3.0 front-panel ports, or simply by USB 3.0 expansion brackets). Connections to these four controllers is conveniently handled by configuring the PCI-Express x4 port from the P55 PCH to work as four x1 ports, apart from the four x1 ports it gives apart from the x4 port. This way, the board is also able to provide three x1 expansion slots and drive the PCI-E GbE controller.

The other expansion slots are two PCI-Express 2.0 x16 (electrical x8/x8, when both are populated), supporting SLI and CrossFire, and two PCI. Apart from the four SATA 6 Gb/s ports (color-coded white), the six SATA 3 Gb/s ports (color-coded blue) are present internally. The CPU socket seems to be powered by an 8+2 phase VRM. The four DDR3 memory slots can take DDR3 modules with frequencies of over 2600 MHz with overclocking. Other connectivity features include 8-channel HD audio and gigabit Ethernet. ASRock will introduce the P55 Extreme4 in a few weeks' time.
